Brief summary
The purpose of this study is to evaluate the efficacy and safety of four interventional pulmonology techniques for the treatment of malignant central airway stricture. The four techniques are: * cryotherapy * argon plasma coagulation * stent * snare
Interventions
use cryotherapy to delete soft neoplasm tissue in the airway
use argon plasma coagulation to delete hard neoplasm tissue in the airway
use stent placement to open the airway compressed by out neoplasm
use snare to delete polypoid neoplasm tissue in the airway
